Sanders came into this debate the front-runner overall, but slightly behind Biden in South Carolina. He was clearly prepared for the attacks that came his way but, as Nate pointed out, also got fired up — bordering on angry — in response to a few jabs. I think the reaction to tonight’s performance will inform his strategy next, either keeping the passion or trying to craft more rehearsed answers. At this point in the cycle, and when you’re in the lead, your campaign has to be nimble.
